Digitally produced, permanent, peel-off decal and methods for producing same

ABSTRACT

A method of creating a digitally printed, water-activated, peel-off and slide-on decal for permanent transfer to an object includes the steps of printing a layer of lacquer on top of a base layer of gum-coated decal paper comprising a cornstarch and dextrose coating having a thickness of between approximately 10 microns to approximately 30 microns, drying the lacquer layer for no more than 90 minutes, printing a full-color artwork with digital, light-cured printing ink in one printing pass onto the lacquer layer to produce a ready-decal sheet having a decal formed by the ink and the lacquer layer, the lacquer layer bonding to the ink and being sandwiched between the cornstarch and dextrose coating and the ink and—having a thickness of between approximately 150 micrometers and approximately 300 micrometers, and—curing the ink with light.

FIELD OF THE INVENTION

The present systems, apparatuses, and methods lie in the field ofdecals. The present disclosure relates to a digitally produced,water-activated, peel-off and slide-on decal, and methods for producingsame, for permanent transfer to an object having various surface typesincluding, for example, ceramic, metal (including stainless steel andaluminum), plastic, acrylic, wood, and glass. Such objects include cups,mugs, glassware, tumblers (such as sport bottles and water bottles), andare, typically, used for retail sales and promotional purposes.

BACKGROUND OF THE INVENTION

Permanent transfer of art to objects, especially promotional objects,has been in existence for many decades. Because permanent adhesion isrequired, modern day decals used with or within promotional products arescreen-printed. A traditional process for creating the decal applies theCMYK process, which is a subtractive color model used in color printingand also is used to describe the printing process itself. CMYK refers tothe four inks used in the color printing: cyan, magenta, yellow and“key” (i.e., black).

In this standard printing process, color separations are generated foreach color to be printed. FIG. 1, for example, shows a color separationdisplay for a magenta negative of this four-color process. This meansthat, for every multi-color design, individual screens must be made foreach color to be printed, which is a significant expense, and which ismultiplied for each screen produced. FIGS. 2 and 3 show exemplaryscreens that are created by taking one of the various color negativesand exposing that negative design to an unexposed sheet of vellum toproduce the actual, physical printing screen that is framed and thenplaced into a screen-printing press and used for transferring one of thecolors to the object to be produced. To burn the negative onto thevellum, the vellum is first coated with a light-sensitive emulsion. Thecolor separation pattern is exposed onto the vellum, resulting in apattern that corresponds to that particular color needed to make thefinal artwork after all of the other colors are printed as well. Becauseeach color and cover layer requires its own screen, there is apossibility that seven total screens need to be produced for any givenartwork, one for white, four for each of the CMYK colors, one for aclear coat (e.g., as a protective layer), and one for a cover coat. Onceall of the screens are produced for each of the colors, they can be usedsuccessively in a screen-printer to create a multi-color final printeddecal, such as those shown in FIGS. 4 and 5. But the final printed decalis not created until every one of the independent color screens is usedand individually printed with the respective color onto the decal basesubstrate.

A typical decal-creation process starts by printing a white base on thedecal base substrate. One exemplary embodiment of the base substrate iswhite gum-coated paper, which is a material that allows the inks tofirst be printed thereon but later to slide off the base after beingappropriately wetted. Such paper typically has a gum adhesive backingthat allows one to create label products for a variety of purposes.Gummed paper requires water to activate the adhesive. Gummed paper ismanufactured with a dry gum adhesive or a dextrin gum adhesive. Once theadhesive is activated, the paper will adhere to the item to be labeled.(Gummed paper is different from a pressure sensitive adhesive paper,which does not require wetting to activate the adhesive.)

As indicated above, for many applications (such as those shown in FIGS.4 and 5), the decal has, as its first layer, a printing of white inkalong the entire surface (or most of the surface) of the gum-coatedpaper. This white base ink layer must be allowed to dry completelybefore any other color can be printed on top of the white background socreated. Each layer of ink is subsequently screen-printed, one color ata time, on top of the white base. Significantly, each ink layer must beallowed to dry individually, thereby, increasing production time anddecreasing overall production throughput. The required drying betweeneach color printing also increases cost. The second-to-last layer to beapplied is a clear varnish that is used as a protective layer for theink layers to increase scratch resistance and protect the colors. Thelast step of producing a prior art decal is to apply a clear overcoat.All of the ink printed prior to the cover coat adheres to the cover coatin this final printing step to produce a finished decal on top of thebase substrate. In this way, the overcoat layer is used as a carrier forthe ink layers so that, when the entire decal is wetted to activate theadhesive of the base substrate, the ink layers protected underneath theovercoat can slide off the base substrate. FIGS. 5 and 6 show an exampleof a finished decal on a base substrate with many different artworksprinted one base substrate and FIG. 6 illustrates a base substrate onwhich is printed a white base layer, all of the color layers, theovercoat layer, and the cover coat. When created using this prior artscreen-printing process, a decal is generated in hours, but it cannot beused for days due to the drying time that is required for the entirecompleted decal(s) sheet before transfer of the decal can be effected.

More specifically, the decal-containing base substrate needs to gothrough a number of post-printing processes. First, as shown in FIG. 7,each base substrate needs to be dried. Because the final decals arewetted in order to transfer them to the object, these substrates need tobe completely dry before further processing of the decals can occur.This drying process takes a considerable amount of time, typically fromfour to eight hours. As multiple decals are present on a singledecal-containing base substrate, processing efficiency requires thedecals to be separated from other different decals by cutting, but onlyafter many of the base substrates are layered together in a stack.Because the decals will be destroyed if the decal-containing basesubstrates stick to one another when placed in a stack, a slip-sheet(e.g., of wax paper) must be placed in between the adjacent sheets. Thisstep is shown in FIG. 8, for example, in which a stack ofdecal-containing base substrates are separated with slip-sheets. Again,this post-processing step adds time, adds cost, and decreases productionthroughput. FIG. 9 shows the stack of decal-containing base substratesin an intermediate post-processing step where groups of decals 1 areseparated from other groups of decals 1 or from individual decals 2.Such cutting typically takes place with a guillotine-type cutter 3.After cutting, as shown in FIGS. 10 and 11, the different projects aresorted, for example, for different customers.

The objects are, then, ready to be decorated with the respectivedecal(s). First, the decal is wetted. This moisture activates theadhesive supplied to the decal from the base substrate to permit the wetfinal sticker to slide off the base substrate and allow a humaninstaller to place the wetted final sticker onto the object before theadhesive fully dries, at which time the decal can no longer be removedwithout destroying the decal or damaging the object, or both. In FIG.12, for example, the object to receive a decal is a water bottle. Thewetted decal is allowed to dry, typically, for approximately two hours.When dry, the installer is then able to and does peel off the covercoat, as shown in FIG. 13 in which the cover coat is partially peeledoff. The object with the installed decal is then heated, as shown inFIG. 14, which heating permanently attaches the ink of the decal to theobject's surface by removing all moisture and hardening the adhesiveand/or ink. All totaled, previous prior art screen-printingprocesses—from first printing of the decal to a final product where thedecal is permanently attached to the object—take four to six days tocomplete.

Digital print processes, as compared to screen-printed processes, printall colors at the same time in one pass. To date, digital printingprocesses have not been able to be used for decals, such as those forpermanent attachment to objects, such as promotional materials. Inparticular, up until a few years ago, nothing was available. Further,LED-cured inks also were not available until about two years ago. Next,the right type of paper of digitally printing decals did not exist.While digitally printed labels existed, for example, in the foodindustry (labels on cans, food products, etc.), they were not resistantenough for promotional products. Accordingly, those of skill in the arthave, to date, not been able to make digital printing processes work forthese printing tasks. In fact, those of skill in the art have indicatedthat it is not even possible to print decals such as these with digitalprinters that print in one-step.

Thus, a need exists to overcome the problems with the prior art systems,designs, and processes as discussed above.

As required, detailed embodiments of the systems, apparatuses, andmethods are disclosed herein; however, it is to be understood that thedisclosed embodiments are merely exemplary of the systems, apparatuses,and methods, which can be embodied in various forms. Therefore, specificstructural and functional details disclosed herein are not to beinterpreted as limiting, but merely as a basis for the claims and as arepresentative basis for teaching one skilled in the art to variouslyemploy the systems, apparatuses, and methods in virtually anyappropriately detailed structure. Further, the terms and phrases usedherein are not intended to be limiting; but rather, to provide anunderstandable description of the systems, apparatuses, and methods.While the specification concludes with claims defining the features ofthe systems, apparatuses, and methods that are regarded as novel, it isbelieved that the systems, apparatuses, and methods will be betterunderstood from a consideration of the following description inconjunction with the drawing figures, in which like reference numeralsare carried forward.

In the following detailed description, reference is made to theaccompanying drawings which form a part hereof, and in which are shownby way of illustration embodiments that may be practiced. It is to beunderstood that other embodiments may be utilized and structural orlogical changes may be made without departing from the scope. Therefore,the following detailed description is not to be taken in a limitingsense, and the scope of embodiments is defined by the appended claimsand their equivalents.

Alternate embodiments may be devised without departing from the spiritor the scope of the invention. Additionally, well-known elements ofexemplary embodiments of the systems, apparatuses, and methods will notbe described in detail or will be omitted so as not to obscure therelevant details of the systems, apparatuses, and methods.

Before the systems, apparatuses, and methods are disclosed anddescribed, it is to be understood that the terminology used herein isfor the purpose of describing particular embodiments only and is notintended to be limiting. The terms “comprises,” “comprising,” or anyother variation thereof are intended to cover a non-exclusive inclusion,such that a process, method, article, or apparatus that comprises a listof elements does not include only those elements but may include otherelements not expressly listed or inherent to such process, method,article, or apparatus. An element proceeded by “comprises . . . a” doesnot, without more constraints, preclude the existence of additionalidentical elements in the process, method, article, or apparatus thatcomprises the element. The terms “including” and/or “having,” as usedherein, are defined as comprising (i.e., open language). The terms “a”or “an”, as used herein, are defined as one or more than one. The term“plurality,” as used herein, is defined as two or more than two. Theterm “another,” as used herein, is defined as at least a second or more.The description may use the terms “embodiment” or “embodiments,” whichmay each refer to one or more of the same or different embodiments.

The terms “coupled” and “connected,” along with their derivatives, maybe used. It should be understood that these terms are not intended assynonyms for each other. Rather, in particular embodiments, “connected”may be used to indicate that two or more elements are in direct physicalor electrical contact with each other. “Coupled” may mean that two ormore elements are in direct physical or electrical contact (e.g.,directly coupled). However, “coupled” may also mean that two or moreelements are not in direct contact with each other, but yet stillcooperate or interact with each other (e.g., indirectly coupled).

For the purposes of the description, a phrase in the form “A/B” or inthe form “A and/or B” or in the form “at least one of A and B” means(A), (B), or (A and B), where A and B are variables indicating aparticular object or attribute. When used, this phrase is intended toand is hereby defined as a choice of A or B or both A and B, which issimilar to the phrase “and/or”. Where more than two variables arepresent in such a phrase, this phrase is hereby defined as includingonly one of the variables, any one of the variables, any combination ofany of the variables, and all of the variables, for example, a phrase inthe form “at least one of A, B, and C” means (A), (B), (C), (A and B),(A and C), (B and C), or (A, B and C).

Relational terms such as first and second, top and bottom, and the likemay be used solely to distinguish one entity or action from anotherentity or action without necessarily requiring or implying any actualsuch relationship or order between such entities or actions. Thedescription may use perspective-based descriptions such as up/down,back/front, top/bottom, and proximal/distal. Such descriptions aremerely used to facilitate the discussion and are not intended torestrict the application of disclosed embodiments. Various operationsmay be described as multiple discrete operations in turn, in a mannerthat may be helpful in understanding embodiments; however, the order ofdescription should not be construed to imply that these operations areorder dependent.

As used herein, the term “about” or “approximately” applies to allnumeric values, whether or not explicitly indicated. These termsgenerally refer to a range of numbers that one of skill in the art wouldconsider equivalent to the recited values (i.e., having the samefunction or result). In many instances these terms may include numbersthat are rounded to the nearest significant figure. As used herein, theterms “substantial” and “substantially” means, when comparing variousparts to one another, that the parts being compared are equal to or areso close enough in dimension that one skill in the art would considerthe same. Substantial and substantially, as used herein, are not limitedto a single dimension and specifically include a range of values forthose parts being compared. The range of values, both above and below(e.g., “+/−” or greater/lesser or larger/smaller), includes a variancethat one skilled in the art would know to be a reasonable tolerance forthe parts mentioned.

Herein various embodiments of the systems, apparatuses, and methods aredescribed. In many of the different embodiments, features are similar.Therefore, to avoid redundancy, repetitive description of these similarfeatures may not be made in some circumstances. It shall be understood,however, that description of a first-appearing feature applies to thelater described similar feature and each respective description,therefore, is to be incorporated therein without such repetition.

Described now are exemplary embodiments. Referring now to the figures ofthe drawings in detail and first, particularly to FIGS. 15 to 21, thereis shown an exemplary embodiment of systems and processes for creating adigitally produced, water-activated, peel-off and slide-on decal forpermanent transfer to an object. In the exemplary embodiment, not onlyis(are) the decal(s) produced much faster than prior art screen-printedprocesses, but also many steps are entirely eliminated, which means thatboth the time to produce and the overall expense for creating decals isreduced substantially.

With standard digital color printing, like the printing that individualsuse with modern-day desktop computers and laser or ink-jet printers, theentire, full-color artwork is printed at once. The desired final colorsare not printed as overlays (i.e., like CMYK processes described above),instead the final colors are printed right away, the first time in thefirst pass of printing. Such printing had never been available fortransferring decals permanently to objects to date, such as promotionalproducts, because the desired permanence did not occur. Either the labelpeeled off (entirely or in pieces), and/or the colors deteriorated,and/or the label never adhered in a permanent manner. The exemplaryembodiments described hereinbelow create decal substrates that are ableto be printed digitally, at a reduced cost, and very quickly, in amatter of minutes instead of days.

In this inventive digital printing process, color separations do notneed to be generated for each color to be printed. FIG. 15, for example,shows a full-color, final-version graphic for an example decal artwork10 that is desire to be placed on an object. This artwork 10 is createdby the artist and is never separated into the CMYK components forprinting individual colors. This means that, for every multi-colordesign, individual screens do not have to be made for each color to beprinted, which is a significant savings in expense because the cost ofeach screen is multiplied by the number of colors and/or treatmentsneeded. Not only are the individual screens entirely eliminated, theentire process for separating the colors into the CMYK composites iseliminated entirely as well. In comparison to the prior art, theinventive systems and processes produce a final printed decal in onestep without any screens.

FIGS. 16 and 17 show an example of a final product of decal artwork 10that is printed directly onto a base layer 20 of decal paper in one passof the digital printer 100. The base layer 20 is, in an exemplaryembodiment, a variation of white gum-coated paper having a coating ofcornstarch and dextrose that is between approximately 10 toapproximately 30 microns thick, more particularly, approximately 13 toapproximately 20 microns thick, in particular, approximately 18 micronsthick. Printed on top of the cornstarch/dextrose layer is a layer oflacquer as described in further detail below. Together, the cornstarchand dextrose and the lacquer create a bonding chemical that, when wettedwith water, allows the digitally printed ink to slide off the base layer20 and, after attachment, drying, and heating, form a permanent bond toa surface of the product 30 to which the decal is to be applied (see,e.g., FIG. 22). The bond is sufficient to attach permanently to manysubstrates, especially ceramic, metal (including stainless steel andaluminum), plastic, acrylic, wood, and glass, for example.

With this difference in the paper backing, a new first step is carriedout. In particular, a lacquer is screen-printed on the paper utilizing a350-mesh screen having a thickness of between approximately 150 and 300micrometers, more particularly, between approximately 200 and 250micrometers, in particular, approximately 214.6 micrometers (0.00845inches). Accordingly, the cornstarch and dextrose layer is sandwichedbetween the paper backing and the lacquer. As such, when wetted withwater, the water allows the lacquer to release from the paper backingwith the cornstarch/dextrose layer acting along with the lacquer as anadhesive.

In an exemplary embodiment, the lacquer is Type DL170 clear glossmanufactured by Nazdar Ink Technologies. This particular lacquer isdesirable because it has a very fast drying time and has chemicalproperties that allow digital printing ink to bond well to the lacquer.Desirably, the clear lacquer is Nitrocellulose based and Nitrocelluloselacquers produce a hard and flexible finish. In general, Nitrocelluloseis used in plastic film and in ink and wood coatings and, therefore, theinventors discovered that this Nitrocellulose-based lacquer has a strongmechanical bonding with the dextrose/dextrin base. It is noted thatlacquer Type DL170 is a substance that the decal printing industry haseschewed for many years because it was primarily used for making outdoorsignage.

The lacquer is allowed to dry, which takes between approximately 30 andapproximately 70 minutes.

The coated paper 22 (coated with the lacquer) is then placed on adigital printer 100, which is loaded with ink that is, for example ratedas approximately 350% flexible. Then, if a white background is desired,a layer of white is printed over the entire sheet of paper or only atareas where decals are to be printed on the sheet. It is noted that,when a white background is printed before the colors of the artwork 10are printed, the colors visually appear to “pop out” to the eye of theviewer. Thus, a white background is a common desired trait but it is notnecessary for the processes described herein. In a particularlydesirable embodiment, the color inks (including the white background)are UV-LED-cured inks, which dry instantly from the brief ultraviolettreatment. In particular, the inks are cured when exposed by UV LEDs forbetween approximately 1 second and approximately 3 seconds. Oneexemplary embodiment of such inks include the LUS 350 manufactured byMIMAKI USA, which are heat-resistant and flexible.

Next, the entirety of the full-color artwork 10 is printed directly ontothe lacquer (or onto the white background that is already on top of thelacquer) to form a ready-decal sheet 40, a number of which are shown inFIG. 17, for example. It is known that the ink in such printingprocesses dries almost immediately (measured in seconds and notminutes). Therefore, all of the steps that were required previously toeffect separate printing color layers and individual drying times areentirely eliminated and are condensed to a single printing step. Thereare no screens, there are no separations, there are no films, and noslip sheets are required. The color inks bond permanently to the lacquerimmediately. This means that, unlike past printing processes, a clearovercoat layer to adhere all of the inks together and allow the inks tobe removed from the paper is no longer necessary.

Thus, in an exemplary embodiment including the white background, theprinted “sandwich” includes color inks on top of the white background ontop of the lacquer on top of the cornstarch/dextrose on top of the paperbacking. If desired, a single clear layer overcoat of ink can be appliedon top of the lacquer layer to act as a protectant, for example, fromsurface scratching by a user.

Now, a decal 42 from the ready-decal sheet 40 is ready to be applied toa product 30. As compared to the prior art time-intensive processes thatrequire drying time for each of the multiple layers, the digitallyproduced decal 42 herein is produced significantly faster; prior artdecals took, on average, seven (7) to ten (10) days from start ofprinting until final product and the instant processes take fromapproximately 2 to approximately 4 hours from start of printing untilfinal product. In summary, the decal paper 20 is flood-coated with theclear lacquer (which acts both as a carrier for the decal as well as abonding agent to various object substrates), the paper 22 with thelacquer is then placed on a highly-advanced digital printer (such as aJFX200 type printer manufactured by MIMAKI USA) that is loaded withflexible inks (such as the LUS350 inks), and, if desired, a clearcoating is applied above the inks. No other printing operations areneeded. In real time, the decal is generated in a matter of minutes.

After the print is complete, the ready-decal sheet 40 is removed andtrimmed into individual decals 42. In an exemplary embodiment shown withregard to FIGS. 18 and 19, the ready-decal sheet 40 can be cut with adigital cutter 50 (i.e., a plotter) that directly contour-cuts aroundthe actual logo, an finished example of a decal 42 is shown in FIG. 19.This means that the cover coat described with regard to FIG. 13 and wasrequired in prior art processes is no longer needed, which also meansthat the physically intensive, hand-operator required step of removingthe cover coat is entirely eliminated. With the decal 42 cut, it is nowready to be attached to the product 30.

As a general cleaning step, the surface of the product 30 to bedecorated is prepared through the application of primers, flame, oralcohol depending on the material of the surface on which the decal 42is to be fastened.

In a particularly desirable exemplary embodiment, a dishwasher additiveis applied to the surface of the product 30 to be decorated to aid inpermanent adhesion and to resist scratching and wear due to repeateddishwasher exposures. One exemplary embodiment of the dishwasheradditive is Type 80 45160-MM Xpression Dishwasher Agent by FERRO GmbH.Typically, this additive is added to inks that cure in a range of 150°C. to 200° C. In the instant processes in contrast, this additive isbrushed directly on the product 30 (e.g., the metal/ceramic/etc.surface) and the wet decal 42 is applied on top of the additive so thatthe additive will be sandwiched between the decal 42 and the product 30,thereby acting as a bonding agent and/or improving the bonding of thedecal 42 to the product 30.

To start the application process after the additive is brushed on thesurface of the product 30, the decal 42 is placed in water forapproximately 10 seconds. The water activates the glue on the base gumpaper and softens the layers of ink. The decal 42 is slid off the basegum paper and is placed onto the unfinished product 32, an example ofwhich is shown in FIG. 20 (with additional non-installed decals layingin front of the product 30). The decal 42 is allowed to dry in place onthe product 30 for approximately 1 to approximately 2 hours. Any residueor other detritus is cleaned off the product 30 after the decal 42 isallowed dry. As shown in FIG. 20, the unfinished product 32 and thedecal 42 applied thereon are, together, fired in an oven 60 atapproximately 140° C. to approximately 200° C. for between approximatelyforty-five (45) and seventy-five (75) minutes, or more particularly, oneof:

at approximately 150° C. for approximately forty-five (45) minutes;

at approximately 155° C. for approximately forty-five (45) minutes;

at approximately 160° C. for approximately forty-five (45) minutes;

at approximately 165° C. for approximately forty-five (45) minutes;

at approximately 150° C. for approximately fifty-five (55) minutes;

at approximately 155° C. for approximately fifty-five (55) minutes;

at approximately 160° C. for approximately fifty-five (55) minutes; and

at approximately 165° C. for approximately fifty-five (55) minutes.

A finished product 34 is shown in FIG. 21 with the decal 42 permanentlyattached thereto.
